To all'wlwm it may concern:

Be it known that I, RUSSELLHUFF, a citizenof the United States, andresident of Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Hydrocarbon-Motors, ofwhich the following is a specification.- I

My invention relates to motor vehicles and particularly to theconstruction and arrangement of the motor in such vehicles.

In one embodiment of my invention I have shown an internal combustionmotor of the water cooled variety mounted low in the vehicle frame, alow hung'motor being desirable to lower the center of gravity and forother well known reasons. tor vehicles, also, the width of the frame atthe sides of the motor is limited by well established designs and it istherefore neces sary that all the operating parts of the motor shall becontained within a very limited compass. In most water cooled motorvehicles the radiator for cooling the circulatin'g water is placed aslow as possible on the frame adjacent the motor, and where a centrifugalpump is employed to maintain the circulation it is necessary that itshall be placed low also to keep it primed and to get the best results.This pump is of course driven by the motor and constitutes one ofseveral auxiliary devices which the motor drives in its normal operationand in practice it isfound desirable to drive such pump at slightlygreater than crank shaft speed.

Another of such auxiliary devices is a magneto or generator and it isdesirable that this shall be placed conveniently for inspection andadjustment. If a magneto is employed it is also necessary that it shallbe driven at the-same speed as the crank shaft of the mo-- tor. As amagneto or generator is also liable to beshort-circuited by water, it isdesirable to carry it high with the vehicle it will not be so liable toinjury from this cause.

For the above reasons, it will be seen to be'impracticable to secure theresults above indicated by driving the'pump and magneto from thesameshaft, and while this might be in some other respects desirable, itis advantageous to' operate found to be more eachof these aux'liarydevices on a. separately driven shaft. In my present invent-ion, I- haveshown the'shafts of these devices tween: two cylinders of- In mo so thatinfording streams porting section 4 10- which is geared by two-to-onegears to of the crank case.

driven by the same driving gear although the pump is atone side of themotor and placed in low relation thereto and the magnetois at the otherside and located at aconvenient. and accessible position above the frameof the vehicle.

Various advantages accrue in consequence of the construction andarrangement of my motor, and these will appear in the following detaildescription.

In the drawings: Figure 1 is a part sectional view on' a transversevertical plane bea motor vehicle embodying my invention, showing thewater jacket insection; Fig. 2 is an enlarged sectional view of thedriving gear on the valve shaft and the connected driven shafts andbearings; Fig. 3 is an end view of the bracket for supporting themagneto; Fig. 4: is-a section taken on the line 4-4 of Fig. 2; and Fig.5'is a section taken on the line 5-5 of Fig. 1.

1 represents one of the cylinders of a multi-cylinder' motor, thecylinders being cast in pairs so that the water jacket- 2 is common toboth cylinders of a pair for a certain distance between the cylinders asis usual in such motors. The water inlet to the jacket 2 is shown at 3.The cylinders l are bolted to the top of the supporting sec tion 4: ofthe crank case, which section has laterally extending arms on and boltedto the side members of the vehiclc frame 6. These arms and side membersof the frame constitute side'supports for the crankcase and motor. Thecrank shaft bearings 7 are: shown suspended be-- tween" the sectionsection 8 of theorem; case, the crank shaft, connecting rods and pistonbeing omittedin Fig. ,1 for clearness. The bottom of the crank case isclosed by the cover 9 which forms an oil well for splashis understood.

Mounted in suitable hearings in the supis a valve operating shaft thecrank shaft 7, one of these gears being shown at 11. By this means thevalve shaft is-driven by the crank shaft at one-half the speed thereof,whereby the valves are operated as in the usual four stroke cycle motor.This shaft" lO is parallel to the crank shaft 7 and as shown is arrangedat one side The gear 11 has on its 74 and the intermediatelubrication as5 with ends resting are soproportioned that the shaft of the magnetowill be .driven at twice the speed of the shaft 10, and thus at thesame, speed as the crank shaft 7 The gear 16 for driving 1 the pump ispreferably made smallerthan the gear 15 so that the shaft of the pumpwill driven at a greater speed than the mag? neto shaft and crank shaft.As above indi g cated,this greater speed for the pump is de sirable inorder to create a proper circula tion of water aroundthe cylinders.

placed above the side supports 5 and side bars of the frame 6 so that itwill be in con venient position for operation and so that access may behad to it easily. This magneto is supported on a bracket 17 which isbolted or otherwise securely fastened to the supporting section 4 of thecrank case at the opening 18 formed in that case. This bracket isprovided with anextended sleeve 19 projecting within the opening 18 andconstituting a bearing surrounding the shaft 20 of the magneto. The gear.15 is formed integral with or secured to a short shaft 21 having thebearing sleeve 22 extendingwithin the sleeve 19 and between it and theshaft 20, this sleeve 22 having-the outer squared end fitting within theshaft 21 so as to rotate therewith, and havingascrew-threaded endadapted to receivethe nut 23 for holding the parts together. The-sleeve22 is secured to the. shaft 20 by any suitable meanssuch as the pin 24.The shaft 21has an annular flange 25 surrounding the sleeve 19 andengaging the thrust bearing 26 which is placed against a-shoulder 27o'fthe bracket 17.- By this meansthe end thrust caused by the engagementof the spiral teeth on thegears 11- and 15gis taken up by the bracket.

17 through the 'thrustbearing- 26, and is not transmitted to themagneto. The magneto furthermore being carried on the horizontal platfogn of the bracket 17 has a fixed and definite relation tothe bearingformed in the sleeve 19 of that bracket, and therefore the parts may beso adjusted that theshaft of the magneto will accurately fit in thebearing and it is not necessary tohave adjustable, means f0 couplingtheshaft of the magneto to the'shaft which drives it. The drivingconnection for the shaft of them-agneto being made through the squaredend of the sleeve 22 permit-s longitudinal {gif'dIjliSt- Man. News...

formed with or carried by a short shaft 28 which is mounted to turn inan elongated. V I sleeve 29 of a bracket 30, which braehetis-willgiriyen ate greater. speed thais the placed in an opening 31 inthe-supporting section 4 of the crank case,'fand"issecured to that caseby any suitable means'such as bolts. The sleeve'29 is formed with as'houL der 32, facing outwardly n arits end; and"a thrust bearin 33 fitsaga' st this shoulderv and is engaged v driving gear 16 for the pump islow in the It will be observed that the magneto 13 is crank case, and isopposit'e the side supports 5 and 6, and that the pump 14 is on'theopposite side ofvthe crank case between the side member 6 and that case.The pump is thus not only in convenient positi'on out of the way, but isso low that it will be kept primed by gravity. Since the pump is so farremoved from the driving shaft 10 and since it is placed down oppositethe side supports it is necessary to have a driving shaft of peculiarconstruction which will enable it to be easily removed from the machine.It is impossible to-have a single long driving shaft adapted to beremoved only by drawing-it fromthe case longitudinally, since the sidesupport is in. thefw'ay. As shown in the drawing, T useashaft 36extending across sli htly in relation to the shaft 28, thus furnishingpractically a universal joint between the parts. The opposite end ofthis shaft 36 is mounted in abearing 38 held in an open.- ing 39 'byscrew 40. Thev shaft 41 of the pump tits in a socket formed in- -the endof the shaft 36 andthe parts are secured so that they will rotatetogether by any suitable means, such as pin 42.

The pump l4 is of the rotary type and is carried on a bracket 43 securedto the section 4 over the opening 39 b any suitable means such as bolts.The end of this bracket has an openingi44 for the passage of the shaft36; v The bracket also has the side webs 45, 46 on opposite sides of theshaft 41, and these webs are preferably formed integral with the-cover47\ofthe pump. It willb'e observedthat this form of bracket facilitatescenteringthe pump in line with its drive shaft 36 and furnishes simpleand efficient xneans for properly supporting'it in positioi. The gear 16for driving the pump is preferably made of less size than the gear 15 onthe magneto shaft so; that the pump.

on the outer side by a cap 34. carried by the outer end of the shaft'28, and thus the end thrust on the shaft 28 caused by the. engagementof the inclinedor spiral teeth on the gears 11 and '16 is taken up bythe bracket 30 through the-thrust bearings 30 having be driven having asleeve fitting in said crank case prov 'having a sleevefitting in saidshaft opening having and adapted to support operating mechanism, and ashaft for operating said mechacrank case provided with a shaft openingcrank shaft and it will be clear that it can at any speed desired byusing a gear of proper size.

It is believed that theoperatio-n and ad; vantages of the device will beapparent to those skilled in the art from the above description.

It will also be understood that the various features .of my inventionare not confined to the particular form and arrangement shown having asleeve fitting in said shaft opening and adapted nism', a shaft foroperating said mechanism having a bearing in aid sleeve, an end thrustbearing on said shaft engaging said sleeve, a spiral gear on said thegear case, and an .intermeshing gear for driving said shaft.
